ICD-10 Code H95.8 – Other intraoperative and postprocedural complications and disorders of the ear and mastoid process, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H95.8 – Other intraoperative and postprocedural complications and disorders of the ear and mastoid process, not elsewhere classified
What it is
This code identifies ear or mastoid complications or disorders that occur during surgery or after a procedure and do not fit a more specific category. Use it when the documentation describes an ear-related postoperative problem but gives no narrower diagnosis.
Clinical signs
Clinical features vary; refer to documentation. You may see notes describing postoperative ear pain, swelling, drainage, hearing change, or another complication tied to a recent ear or mastoid procedure.
When to use this code
Use H95.8 when the record links the condition to an intraoperative or postprocedural complication involving the ear or mastoid process and no more specific code is documented. It is appropriate when the provider clearly identifies the complication but does not name a precise postoperative diagnosis. Check documentation for the procedure and timing.
Do not use for
Do not use this code for routine postoperative follow-up, expected healing, or a complication that has a more specific ICD-10-CM code. Do not assign it when the ear problem is unrelated to a procedure.
Coding tip
Code the documented complication first, and verify that the note ties it to the procedure rather than to a preexisting ear condition.
